Cover letter [PATCH v2 0/2] ACPI: Fix a regression of the table checksum verification.
From: Lv Zheng <[email protected]>
There is a warning message triggered by the early table chekcusm verification during boot. Large tables cannot be installed on x86 platforms due to this failure. The root cause is the size limitation of the current x86 early mapping implementation, it's thus not suitable to be used to map ACPI tables.
This patchset fixes this regression by stopping verifying table checksums during the early boot stage.

mapping size limitation.
